Abstract: Lithofacies vary significantly in alluvial fan, and this results in serious reservoir heterogeneity. Geologic models that are based on sparse wells or core data are potentially inaccurate descriptions of the reservoir. While incorporating seismic data and using geostatistical method, the spatial variability of reservoir parameters can be better characterized. Arial variogram models of any position and direction are available for accurate quantitative geologic reservoir models. This technique integrates the vertical high resolution data of well and lateral high resolution data of seismic. The inversion section, such as SEISLOG, is used as soft constraining data here to provide stratigraphic framework and spatial varying characteristics of reservoir parameters while establishing determining reservoir models,and seismic records are regarded as hard data in stochastic simulation to asses the reliability of those final realizations.
